MAGNETIC SEPARATOR.

SPECIFICATION forming part Of Letters Patent NO. 383.863, dated June 5,1838.

Application filed September 23, 1887. Serial No. 250,511. (No model.)

To all whom it may concern..-

Be it known that I, GURDON Commune, a citizen of the United States,residing at Glens Falls, in the county of XVarren and State of New York,have invented new and useful Iniprovements in Machines for EliminatingImpurities from Magnetic Iron Ores and other Materials, of which thefollowing is a specification.

This invention relates to a machine which is intended principally forconcentrating magnetic iron ores in an economical manner, but which canalso be used for separating iron filings from non-magnetic matter.

The peculiar and novel construction of my machine is set forth in thefollowing specifica tion and claims, and illustrated in the accompanyingdrawings, in which Figure l is a plan view, some portion being brokenaway to expose the parts below. Fig. 2 is a vertical section in the linea: :0, Fig. 1, looking in the direction of the arrow opposite to thatline. Fig. 3 is a similar section in the line y y, Fig. 1, looking inthe direction of the arrow opposite to'that line.

Similar-letters indicate corresponding parts.

In the drawings, the letter A designates a frame which forms thebearings for four roll ers, B B B B. The rollers B B support the primaryendless belt or apron D, and the rollers B 13 support the secondaryendless belt or apron G, which runs transversely to the apron D. E is ahopper placed over the primary apron I). In proximity to secondary apronO are placed one or more magnetized plates, F. These plates are madepreferably of hardened steel, and by placing upon them one or moremagnets, G, they become magnetized. The magnets G may be permanentmagnet-s or electromagnets. The plates F are secured to traverses F,which are connected by screws a a to the frame A, so that by means ofsaid screws the plates F can be raised or lowered. A hopper, H, isplaced in suitable relative position to the secondary apron C, (see Fig.3,) and a brush or scraper, I, acts on said secondary apron. Suitablereceptacles, J K, are provided one for the concentrated ore or ironparticles and the other for the gangue or refuse. A belt, N, whichextends round pulleys L M, is madeto impart motion to the aprons G D.Said belt passes over guide-rollers O 0, Figs. 1 and 3.

The machine operates as follows: The ore or material to be treated iscrushed'or pulverized and fed to the primary apron D through the hopperE, so as to form a thin layer on said apron. As the apron is moved inthe direction of the arrow thereon in Figs. 1 and 2, the layer ofpulverized ore passes slowly beneath the magnetized plates F, and theiron contained in said layer being attracted by said plates is caused toadhere to the secondary apron O, which moves in the direction of thearrows shown thereon in Figs. 1 and 3. As this secondary apron movesalong, the particles of iron adhering to it are carried over the hopperl, and they drop down through this hopper into the receptacle J beingseparated from the apron either by their inherent gravity or by theaction of the scraper I. The non-magnetic particles in the layer formedon the primary apron D are dropped into the receptacle K.

My machine can be used for concentrating iron ores of different kinds,and I have found it very useful in treating magnetic iron orescontaining phosphorus or titanium.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a primary apron, of a secondary apron tooperate transversely to the primary apron, a magnetized plate secured inproximity to said secondary apron, so as to draw the i on particles tosaid secondary apron, and suitable driving mechanism for actuating theaprons, substantially as set forth.

2. The combination, with a primary apron and a secondary apron made tooperate transversely to the primary apron, of a magnetized plate securedin proximity to said secondary apron, so as to draw the iron particlesto said. secondary apron, suitable driving mechanism for actuating theaprons, and a scraper or brush made to act on said secondary apron,substantially as set forth.
